This:y invention relates; to-l improvements. `in Watercoolers used., inconnection Witlr circulatingf systems and. has as one off its objects toprovide a. cooler, or preferably a series. of the. same, so. arranged.Within a tank.4 or refrigeratng. chamber as to. presentits entireexterior.- tothe effects. of the refrigerant, assice` packed. inthetank.

Another purposeis. to produce a cooler. unit made. inil sections and sodesigned as to avoid machine Work except for the Water inlet. andloutlet, these, sections permittingV ready. separationatany. desiredtime., l

A. further. aim. isv inthe provision. off'means` for Washing. theinterior of the cooler units in. aV thououghmanner, removal ot;sediment. and. theflike, without, separation of. the sections. or.vremoval. of` the same from. the tank.

A. stillurther object. istocombine with, one. or more ot the waterVinlet pipes a. regulating` valve whereby. the pressure mayy be reducedasrequired.

These and other' like aims, objects` and.

purposes, such. as. economy. in: construction, neatnessl of appearance,:compactness and. general.. utility, are accomplished b v the novel;construction, combination and. arrangement of.. parts. hereinafterydescribed and shown.. in. the accompanying drawing, conv stitutingT amaterial partvoi this disclosure, and..in. whicluc Figure. lis a`fragmentary sectional view of afconventional form. ot. ice tank,showtwoof thev cooler units therein,one being in... section. and theother ini side eleva,n

These cooler. unitsmav rest directly on the. flooring` 10 orpreferablyupon4 p1`ates'2'8. At points. adjacentl the. bottoms of' the. lowerelements 15 screw-throaded` openin s Serving as washout, are madethrough. t `e `Wall` and supplied with. plugs 29,. readilgv`removablewheni cleansing the interior..

The. laterali openings` in the, bosses. inter-` sect longitudinal.openingsy 37.' and. 38', in'. the` manner4 of T fittings, the. outeropenings lli recaer/i being fitted with plugs 39 and 40, the inneropening in the boss 30 communicating directly with the tank as shown inF ig. 1.

Engaged in the opening 37 of the mating boss 31 is a tube 4l extendingfar down into the lower element l5 and fixed in the body of a reducingvalve 42.

Said valve body contains a screw-threaded opening 43 in its lower end inwhich is an adjustable plug 44 having a bore 45 in its upper end, thelower end being provided with an extending rim 46 by which it may beturned to advance the plug up or down in the head 42.

A plurality of relatively small transverse openings 47 intersect thereduced bore 48, above which is a shoulder or valve seat 49 adapted tohave the sphere or ball 50 make contact, closing the opening 5l at theend of the tube 4l.

A plunger 52 supportingly receives the ball 50, the plunger and ballbeing freely movable and carried at the end of a stem 53, encircled by acompression spring 54 located in the bore 45 of the plug.

Thus more or less pressure can be applied to the ball, which resistingthe force of the incoming stream of water, reduces the same to therequired pressure.

lt will be obvious that only one of the reducing valves need be used andthat preferably on the first inlet tube, but that if a separate head beused in each cooler unit, the water will be kept in a state of agitationwhen in operation.

There severa-l units are used they will be interconnected as indicated,unions being used in the pipes so that substitution can be easilyeffected, without disturbing the assemblage of the cooler units, anynumber of which can be used in consecutive relation.

Due to the relative large surface of the coolers exposed to the ice, thewater passing through the pipes is quickly and effectively cooled at aminimum of expense, and as has been seen, the cooler units can becleaned in an expeditious and eiiicient manner.

Although l have described my improvements with considerable detail andwith respect to certain particular forms of my invention` I do notdesire to be limited to such details since many changes andmodifications may well be made without departing from the spirit andscope of my invention in its broadest aspect.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

l. A cooler unit comprising two substantially equal, hollow conicalelements having respectively tenon and socket interengaging surfaces attheir base edges, paired lugs extending laterally from their adjacentoutstanding edges, one of each pair of lugs being forked and the othercylindrical, eye

bolts engaging cireumferentially around the cylindrical lugs andadjustable within forks of the mating lug, means for the inlet andoutlet of water to said units, and means for discharging the contents ofsaid unit formed in one of said sections.

2.1K cooler unit comprising two equal, hollow conical elements havinginterengag ing surfaces at their base edges, removable clamping meansfor sections, said unit being disposed in a vertical plane, means forthe entrance and exit of water to the upper of said sections, a tubeengaging the inlet means to extend into the lower of said sections, ahollow head en the inner end of said tube, said head having a pluralityof lateral openings, a spherical valve seat in said head, a manuallyoperable screw engaged in said head below the seat, said screw having anaxial recess, a spring in the recess, a plunger resting on the spring, aball valve seated on said plunger adapted to close against the valveseat and removable means in said lower section for discharging thecontents of said unit.

3. A cooler unit comprising hollow conical elements having interengagingsurfaces at their contacting base edges, a packing ring interposedtherebetween, forked radial lugs on one of said elements near the basethereof, cylindrical projections on the other element registering withsaid lugs, said projections having notches in their outer surfaces,bolts having eyes encircling said projections engaging in the mentionednotches, the bodies of said bolts passing between the forks of saidlugs, nuts on said bolts for rigidly clamping said sections together,inlet and outlet means on the upper of said sections, a drain in thelower section, a tube extending from said inlet means into the lowerportion of the lower element, a cylindrical head fixed on said tube toextend downwardly, said head having a plurality of radial openings inits upper end, a spherical valve controlling the passage through thementioned openings, a spring normally tendtwo equal,

ing to press said valve against its seat said seat being above theopenings, and means for manually adjusting the action of said spring.

4. A cooler unit comprising two equal, hollow conical elements havinginter-engaging surfaces at their base edges, a packing ring interposedtherebetween, a pair of bosses on the outer end of said upper element,said bosses having inreaching and intersecting lateral openings, inletand outlet pipes fixed in the mentioned lateral openings, a tube engagedin the bore of the boss containing the inlet pipe, said tube extendingpast the joint between said sections, an adjustable reducing valve inthe end of said tube and manually operable means for adjusting saidvalve.

5. A cooler comprising in combination with an ice container, of a seriesof hollow conical units formed of substantially equal sections disposedin said container, releasable lneans ioi clamping said sections in rigidengagement, inlet and outlet openings on one of each of said sections,and connections from the inlet openings of one section extending to theopposite ends ofthe other sections whereby a liquid may be progres- 10name to this a-p lioation.
